mCanWaterWalk was set to false and updated during next frame's simulation
mOnGround is set to true but then was updated as part of the scene
loading logic.
Instead of explicit work queue stop before any possibly used engine manager
is destructed. Based on an assumption that any engine manager can be destructed
independently from the work queue destruction. This model is already used in
CellPreloader that conflicts with explicit work queue stop.
After the work queue is requested to be stopped, any client waiting for a not
started work item to be done will wait forever because the work item is dropped
from the queue. Therefore either clients should not wait for own work items to
be completed in destructor or the work queue should not drop items before
clients are destructed. Other approaches are possible but are not considered
due to increasing complexity.
CellPreloader already tries to wait for all created work items to be done so
keep it that way and extend the model to AsyncScreenCaptureOperation and Scene.
Additionally abort all scheduled work items when owner is destructed. This
prevents a long exit when multiple screenshots are scheduled right before
exiting the game.
Since actors can be active in 3x3 grid around the player, we need to
first load all objects in a 5x5 grid around the player.
Split load and unloading in 2 phases. Add an mInactiveCells set into the
scene, which contains all cells inside the aforementioned 5x5 grid.
These cells contains only heightfields and non-animated physics objects.
Animated objects are tied to the scene graph, which doesn't exists yet
in these cells, so we skip them.
To fix all possible situations when active message box overlaps with loading
screen progress.
The only used condition to center loading screen progress by height is
number of message boxes > 0. No need to pass it through interface.
LoadingScreen can check it inside setLabel function.
Add special loading progress bar.
It should be fast enough to not keep loading screen for noticably long but
will provide better pathfinding for actors inside interior cells.
A prerequisite to create physics objects for statics was to remove the
dependency on base node (since it doesn't yet exists) for object
position. It is still necessary for animation though.
Restore the basenode (and the associated FIXME) so that animated objects works properly.
Since actors can be active in 3x3 grid around the player, we need to
first load all statics in a 5x5 grid around the player.
Split load and unloading in 2 phases. Add an mInactiveCells set into the
scene, which contains all cells inside the aforementioned 5x5 grid.
These cells contains only heightfields and physics objects of static
class.
loadCell always adds a height field, but unloadCell only removed it for
cells with height data. Reloading a cell overwrote the height field
added earlier (leading to its destruction) while the navigator retained
a reference to the now deleted collision shape, leading to a crash.
